I have no clue why, but if I play for a prolonged time on TU, it restarts my computer with no reason. This doesn’t happen with other games. I was able to complete Overdrill on PAYDAY 2, which requires an hour to do. Tower Unite restarts my computer if I leave it open for 45 minutes. It leaves no crash report that I can find. I’m guessing this could be a problem with the engine, but I’m not sure.

Did you overclocked your RAM recently?
If this is your issue maybe the problem is that your BIOS is not stable with your RAM frequencies, check CPU-Z to set the proper timmings to your RAM, if that doesn’t work, try to update your BIOS or lower your RAM frequency.
